#### DCC Alignment Creation for QuickAlign

For measuring machines capable of DCC operation, QuickAlign can automatically define a DCC alignment by duplicating the features and rough manual alignment commands in DCC mode in order to get a more accurate alignment.

DCC alignment creation can occur if these conditions are all met:

- PC-DMIS is in startup mode.

- PC-DMIS is connected to a DCC-enabled machine.

- The measurement routine is in manual mode.

- The features you choose for the alignment fully constrain the six degrees of freedom.

How the DCC QuickAlign Functionality Works

The QuickAlign DCC functionality does the following:

- Adds an operator comment command (COMMENT/OPER), to remind the operator to add all needed collision avoidance commands.

- Adds a mode command to change to DCC mode (MODE/DCC).

- Copies all the feature commands used for the manual alignment, along with any feature commands they depend on, and pastes them using the same name as their original feature names, appended with "_DCC".

- If the manual features are auto features and the probe type used is a scanning probe and the Use Scanning Strategies for Quick Align check box, from the General tab of the Setup Options dialog box (Edit | Preferences | Setup) is marked then the DCC mode features are created using the scanning strategy defined in the .ipd (inspection plan defaults) file.

- Generates a DCC alignment command after each DCC feature that is a copy of one of the original manual features used to define the final manual alignment. The original manual feature is replaced with its DCC copy in the new DCC alignment. The resulting DCC alignment commands constrain all six DOF. Each generated DCC alignment command is named based on the last manual alignment name appended with _DCC1, _DCC2, and so on (for example, if A3 is the name of your manual alignment, and two DCC commands are generated from that alignment, they appear as A3_DCC1 and A3_DCC2).

- Recalls the STARTUP alignment automatically if the alignment constrains all six DOF. The STARTUP alignment is the default empty alignment at the start of every measurement routine. This means no extra features are added to the dependency list.

- Ensures that all constructed features in DCC mode are constructed using features measured in DCC mode.

- Creates an alignment using QuickAlign with features similar to a manual alignment but is measured and constructed in DCC mode.

- Combines the manual alignments and their associated feature commands into a GROUP command named "MAN ALIGN".

- Combines DCC alignment and its associated features into a into a GROUP command named "DCC ALIGN".
